Welcome to the django-pony-express - class-based emails for Django shipping with a full test suite.

Similar to class-based view in Django core, this package provides a neat, DRY and testable (!) way to handle your emails in Django.

Features

Class-based structure for emails
- Avoid duplicate low-level setup
- Utilise inheritance and OOP benefits
- No duplicated templates for HTML and plain-text
Test suite to write proper unit-tests for your emails
- Access your test outbox like a Django queryset

Etymology

The Pony Express was an American express mail service that used relays of horse-mounted riders. [...] During its 18 months of operation, the Pony Express reduced the time for messages to travel between the east and west US coast to about 10 days.

https://en.wikipedia.org/wiki/Pony_Express

The name of this package combines the Django mascot (a pony) with a once quite successful mail service in the US. Ingenious, right?

Git hooks (via pre-commit)

We use pre-push hooks to ensure that only linted code reaches our remote repository and pipelines aren't triggered in vain.

To enable the configured pre-push hooks, you need to install pre-commit and run once:

pre-commit install -t pre-push -t pre-commit --install-hooks

This will permanently install the git hooks for both, frontend and backend, in your local .git/hooks folder. The hooks are configured in the .pre-commit-config.yaml.

You can check whether hooks work as intended using the run command:

pre-commit run [hook-id] [options]

Example: run single hook

pre-commit run ruff --all-files --hook-stage push

Example: run all hooks of pre-push stage

pre-commit run --all-files --hook-stage push

Update documentation

To build the documentation, run: sphinx-build docs/ docs/_build/html/.
Open docs/_build/html/index.html to see the documentation.

Translation files

If you have added custom text, make sure to wrap it in _() where _ is gettext_lazy (from django.utils.translation import gettext_lazy as _).

How to create translation file:

Navigate to django-pony-express
python manage.py makemessages -l de
Have a look at the new/changed files within django_pony_express/locale

How to compile translation files:

Navigate to django-pony-express
python manage.py compilemessages
Have a look at the new/changed files within django_pony_express/locale

Publish to ReadTheDocs.io

Fetch the latest changes in GitHub mirror and push them
Trigger new build at ReadTheDocs.io (follow instructions in admin panel at RTD) if the GitHub webhook is not yet set up.

Publish to PyPi

Update documentation about new/changed functionality
Update the Changelog
Increment version in main __init__.py
Create pull request / merge to master
This project uses the flit package to publish to PyPI. Thus publishing should be as easy as running:
```
flit publish
```
To publish to TestPyPI use the following ensure that you have set up your .pypirc as shown here and use the following command:
```
flit publish --repository testpypi
```

Maintenance

Please note that this package supports the ambient-package-update. So you don't have to worry about the maintenance of this package. All important configuration and setup files are being rendered by this updater. It works similar to well-known updaters like pyupgrade or django-upgrade.

To run an update, refer to the documentation page of the "ambient-package-update".
